Livestream: Watch Elon Musk at IAC2017 as he reveals Mars plan
Here’s how you can watch a livestream of Elon Musk at IAC2017
After many months of teasers from Elon Musk and SpaceX, Musk is about to give a presentation on SpaceX’s updated Big Falcon Rocket, which is expected to one day bring humans to Mars and potentially even support a city-sized colony on the planet.
Musk’s 2016 presentation on the Interplanetary Transport System captured the imaginations of many people, kindling the sort of excitement he has always hoped to inspire. Sitting in the audience during his Guadalajara, Mexico talk, his esoteric desire to make people excited to get out of bed in the morning resonated with me.
Updated: Elon Musk teases SpaceX-built cities on the Moon and Mars
Nevertheless, we now find ourselves almost exactly one year after his 2016 talk, and many things are believed to have changed with both SpaceX’s interplanetary colonization strategy and the hardware the company expects to develop to accomplish that colonization. Musk has said that tonight’s presentation will focus on the how of SpaceX’s Mars colonization efforts, entailing a somewhat smaller booster and spaceship with “major improvements”, as well as some “unexpected applications” for the vehicle.
Major improvements & some unexpected applications to be unveiled on Friday at @IAC2017 in Australia

What exactly those unexpected applications might be is fittingly unclear, if they are indeed less than obvious. More obvious applications for a fully-reusable heavy launch vehicle include
- More affordable access to orbit
- Mass launches of satellite constellations
- Off-the-shelf access to the surface of the Moon
- Space tourism in Earth orbit
- Cheaper and simpler space stations in a single launch
- Direct and rapid access to the Outer Solar System for more complex planetary exploration missions
These are just a handful of the potential uses and benefits that could be derived from a fully-reusable heavy launch vehicle like the Big Falcon Rocket (BFR). Unexpected or not, the near-Earth utility of a theoretical BFR is undeniable.

Aside from additional information on those unexpected applications, we can expect several exciting tidbits. Musk has teased new and improved videos of their Raptor rocket engine conducting live-fire tests, and we also have reason to believe that his talk will be accompanied by an equally slick and thrilling collection of renders of the updated BFR in action. Mirroring last year’s rather shocking unveiling of physical hardware development in the form of Raptor’s first test fire and a massive carbon fiber propellant tank, I personally expect to see confirmation of still more tangible hardware development.
A growing amount of recent news pointing to Boca Chica, Texas as the first launch site for SpaceX’s massive new rocket may also lead to an official statement from Musk himself either confirming or denying this, maybe accompanied by a tentative schedule for pad development. Regardless of what is revealed, tonight’s presentation is bound to be yet another exceptional opportunity to hear Musk wax poetic about SpaceX’s desire to make humanity a multiplanetary species.

Tesla is delaying its event for the Roadster, moving it from this Thursday, October 1, to Thursday, October 15, due to unfavorable weather.
The company has said it has been tracking the weather for this Thursday closely with local meteorologists, and because the event can only be held outside, Tesla is making the call to delay it:
“We’ve been tracking the weather closely with local meteorologists, but given the severe conditions predicted & because this event can only be held outdoors, we’ve made the difficult decision to reschedule. New date is October 15. Additional details to follow.”

We are sure that this is bringing back PTSD for some Tesla fans, and we know it is not ideal, but this also reveals some things about the event. Tesla said that this can only be held outdoors, meaning it bodes well for the rumors that the vehicle could potentially hover.
Some believe that this was essentially confirmed by the FAA airspace restriction they were granted, but this could have been for a drone show or to keep drones from spying on the event.
Tesla Roadster is available for order once again following brief hold
The Roadster event has been long-awaited, and it is unfortunate that the weather is going to keep us all waiting a little bit longer.
The Tesla Roadster will be unveiled in Waco, Texas.

SpaceX turned a heralding moment for Starship into its greatest
Starship reached orbit despite losing an engine, deployed 26 Starlink V3 satellites on Flight 14.
SpaceX’s Starship reached orbit for the first time on Monday, and for a few nail-biting minutes it looked like it wouldn’t. During ascent on Flight 14, one of Ship 41’s six Raptor engines shut down early, and SpaceX’s livestream host Dan Huot told viewers the team had decided not to commit to orbit. Minutes later, after what Huot described as a lot of conversation in the control room, the final poll came back in favor, and a roughly 19 second burn of a single Raptor pushed the ship into orbit about 170 miles up.
The reversal matters because SpaceX had written the exit ramp into the mission plan. The company said it would only fire the orbital insertion burn if flight controllers confirmed enough backup hardware remained for the deorbit burn, a condition Teslarati laid out ahead of the flight. Losing an engine was exactly the scenario that rule was built for.
Pressing forward fits Elon Musk’s history. Falcon 1 failed three straight times before its fourth launch reached orbit in 2008, with SpaceX nearly out of money, and Starship was developed by flying prototypes until they broke. What changed this year SpaceX going public, and with $SPCX sliding below its IPO price in July when Flight 13 slipped, the short interest climbed significantly, as Teslarati reported at the time. A Starship potentially lost today with revenue generating next-gen Starlink satellites aboard would have landed directly on shareholders.

That pressure showed up after orbit. SpaceX cut a flight planned to last nearly 10 hours to about three, moving splashdown from west of Chile to the North Pacific near Hawaii. SpaceX gave no reason, though Musk said this month the company was being extremely cautious about debris risk. The single Raptor for deorbit worked, and Ship 41 completed its flip and landing burn before breaking apart in the water, an outcome SpaceX expected. Musk has structured SpaceX’s governance to shield long term bets from market pressure.
The payload is the bigger business story. Musk posted that all 26 Starlink V3 satellites deployed and are “operating nominally.” Each V3 is rated for about 1 Tbps of downlink and 160 Gbps of uplink, so this single launch adds roughly 26 Tbps, about 10 times what a Falcon 9 load of V2 Mini satellites adds. The V3 is too large for Falcon 9, making Starship the only vehicle that can build out the planned 100,000 satellite constellation, at up to 60 per flight once it reaches routine service. Unlike the 20 V3 units on Flight 13, which reentered on a suborbital path, these will raise their orbits and could begin serving customers within weeks and bring in hundreds of millions of additional dollars in projected Starlink revenue.
SpaceX has already begun winding down Falcon 9 Starlink launches from Florida in favor of Starship. Reported targets put Flight 15 as early as October 19, leaving about three weeks to diagnose Monday’s engine shutdown before the next orbital attempt.

Tesla quietly doubled the size of its Cybercab fleet within the Robotaxi program in Austin, Texas, over the weekend to well over 100 units.
The move not only establishes more of the steering-wheel-less and pedal-less vehicles within the ride-sharing fleet Tesla has been operating for a year, but it also solidifies a more robust Robotaxi fleet as a whole.
Riders started receiving notifications from the Robotaxi app that stated: “Cybercab fleet has doubled: more rides available.”
I got this notification on the robotaxi app. They are saying the Cybercab fleet has doubled. Glad that they are advertising this pic.twitter.com/FFrnw4FRCF

Tesla first launched rides in the Cybercab in early September, although the Robotaxi fleet has been active for over a year, as rides began last Summer. Cybercab is truly Tesla’s most crucial vehicle release yet, as it is the first car any company has built that is geared toward full-fledged and end-to-end autonomy, never needing human intervention for anything.
Only available in Austin at the current time, Cybercab has two seats and has been spotted testing around various U.S. states and regions; Tesla plans to deploy the Cybercab in various U.S. cities in the coming months as a best-case scenario.

The availability of the Cybercab has doubled from just 58 units last Monday to 125 the following Friday. Marking a substantial increase in Cybercab availability, the additional ride-sharing units are more than welcome, as wait times for Cybercabs, especially, were quite high.
The dramatic increase is a sign that demand for Robotaxi is growing and Tesla is feeling more confident that its driverless ride-hailing suite, especially its Full Self-Driving software, is able to handle any traffic situation without explicit direction or supervision from a human being.
